WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 387,605, dated August 7, 1888.

Application filed November 1, 1987.

To all whom it may concern:

Be it known that I, CHARLES H. S'romnirr, of New York city, New York, have invented certain new and useful lmproven'ients in Fountain Attachments for \Vash-Boilers, of which the following is a specification.

My invention relates to that class of portable devices which are designed to be placed in wash-boilers to produce an energetic fouutainlike action of the water,which thus circulates among the contained clothes with a cleansing effect. These devices usually consist of a base portion of inverted cup or pan like character which rests upon the bottom of the boiler, and which is provided with an inlet and outlet, a tube rising from the outlet and terminating in an elbow. The cooler water entering the base pan or chan'iber by means of the inlet therein becomes highly heated in this confined space and, seeking an outlet, rushes up the tube and is forcibly discharged down upon the clothes by means of the elbow.

arious constructions of the base pan or chamber have been heretofore produced, and one species thereof employsa volute or tortuous passage between the inlet and outlet, along which the water rushes in its passage to the discharge tube. This tortuous passage and its inclosing-chamber have heretofore been con structed in several different ways. In one construction the pan and the tortuous passage were made of cast metal cast integrally in one piece, while in another the parts were also of cast metal cast separately and bolted together. Still another construction employed an inverted cup of sheet metal, the volute or spiral partition being also of sheet metal soldered in place, while a lead weight was attached to the cup to give the device steadiness and hold it in place in the boiler. Now, my invention aims to greatly simplify and cheapcn the construction of such fountains; and it consists in the special construction and arrangement of parts, which, briefly, consist in the combiner tion,with the sheet-metal cup or pan, of a castmetal volute'chamber secured to the pan by bolts or other fastening, thus dispensing with any extraneous weight, and consequently rendering the construction simple, cheap, and durable.

The castinetal chamber is terminated with a central tubular neck which rises through a Serial No.2531ll8. lllfndr-l.)

cates the generatirig-chamber,which is open at the bottom,as usual, and adapted to be placed on the bottom of the boiler. The interior of the generating-cliamber has a volute, spiral, or other tortuous partition, b, leading to the center, from which the tube 0 rises, which tube is made in two sections, one sliding on the other, as seen in Fig. 2, to admit of extension or contraction, the upper section, 0, being terminated in an elbow to deflect the rising stream of water over the clothes in the usual way. Now, the generating-chamlver a is made of a common stamped tin orsheetmetal baki ng-pan inverted and having a circular hole punched centrally out of the bottom and a flap, (1, cut out of the rim, which is bent inwardly, thus forming a circumferential opening or inlet, 6, at the rim and a central outlelgf, in the bottom of the pan,which becomes the top of the generatingchamber, as seen best in Figs. 2 and 3. The volute or tortuous partition 71 is made of cast metal, preferably cast-iron, which is cast integral with a top plate, g, having a central tubular neck, 71, which snugly fits and rises through the central opening cut in the pan (1, as best seen in Fig. 2, and receives the tube 0, while the outer ends of the top plate are secured to the bottom of the pan by two studs, i i,which pass through both parts and receive nuts on the under side, as seen in Fig. 2, thus securing the castiron partition firmly to the sheetmetal pan in a simple and inexpensive manner.

It will be seen in Figs. 1. and 3 that the flap (,Z,which is cut out of the rim or side of the pan to form the inlet 0, is bent inwardly and rests against the circumferential or initial part of the spiral partition I), which at its outer end closely approaches the circumference of the pan, while its inner end terminates near the eenter of the pan adjacent to the outletf, thus forming a spiral water-passage from the eireumferential inlet (2 to the central out let, f, as best seen in Fig. 8.

It will be seen that the flap (l, resting tightly on the partition I) and pressing like a spring tlap or valve thereon, covers the joint between the partition and the panand insures asmoother and more integral inflow of water at the inlet a, and, besides, the spring-[lap (1 tends to hold the casting firmly in place, taking up any play in its fasteningpserewsand thus prevents looseness or rattle of the parts under the foaming action of the water.

it may now be appreciated that this eonstruetion is not only very simple, strong, and durable, but it dispenses with all soldering in the formation and attaehment of the spiral partition with the pan, and as the same is formed of east-iron, and is hence quite weighty, it thus dispenses with a separate weight and forms partition and weight in one. This east partition, being-secured to the pan by screws or other fasteningsfls much stronger, more durable, and inexpensive than a partition made by soldering, and it thus serves to hold the fountain more steadily in the boiler by reason of t and neck 11, with fasteniug-boltst' i and tube e, si bstantially as shown and described.
